Ghi chú thiết kế
Ensure all VDD and VDDA pins are connected to a clean power supply with decoupling capacitors (100nF and 4.7uF) placed close to the pins. The device operates from 1.7V to 3.6V, and proper decoupling is critical for stable operation, especially when using the ADC and DAC peripherals.
For the LQFP-64 package, use a 4-layer PCB with a solid ground plane. Place the crystal oscillator and load capacitors close to the OSC_IN/OSC_OUT pins to minimize parasitic capacitance. Keep high-speed communication lines (USB, Ethernet) impedance-matched and away from noisy traces.
Do not leave unused GPIO pins floating; configure them as outputs or enable internal pull-ups/pull-downs to avoid excessive current consumption. Also, ensure the NRST pin is properly pulled up with a 100nF capacitor to ground to prevent spurious resets.
